Do Betta fish kill guppies?


Betta fish and guppies are both popular fish species that are often kept in home aquariums. However, there is a common misconception that betta fish will kill guppies if they are housed together. So, do betta fish kill guppies?

The answer is not a straightforward yes or no. It depends on various factors such as tank size, gender, temperament, and the number of fish in the tank. Bettas are known for their aggressive behavior, especially towards other fish with long, flowing fins that resemble their own. This includes male guppies, which have long tails and fins. If a male betta is placed in a small tank with a male guppy, there is a high chance that the betta will attack and kill the guppy.

However, female bettas are less aggressive than males and can be kept with guppies in larger tanks. The key is to ensure that the tank is big enough and has plenty of hiding places and plants to create separate territories for each fish. It is also important to avoid keeping too many fish in the same tank, as overcrowding can lead to aggression and stress.

It is worth noting that bettas are solitary fish and prefer to live alone. Therefore, it is always recommended to keep them in their own tank rather than with other fish. If you do decide to keep bettas and guppies together, it is crucial to monitor their behavior closely and separate them immediately if any aggression is observed.

In conclusion, betta fish can kill guppies, but it is not always the case. The likelihood of aggression and violence depends on various factors, and it is essential to provide a suitable environment for both species to coexist peacefully.
